Anthropic IPO Eyes $2 Trillion Valuation After $42 Billion Loss

A record listing built on a record loss

Anthropic, the maker of Claude, is preparing what could become the largest stock market debut ever. It is doing so after reporting the biggest annual loss of any company that has tried to go public. Bloomberg reported that the San Francisco company showed investors its third-quarter results at its headquarters on Wednesday. Revenue reached $16.8 billion, up about 46% from $11.5 billion in the prior quarter, and the company booked an adjusted profit. The IPO is planned for November and could value Anthropic at as much as $2 trillion.11 The company filed confidentially with US regulators in June and wants to list once the US midterm elections are over. Goldman Sachs and Morgan Stanley are reportedly leading the deal.11

The loss is what makes the story stand out. Reuters reviewed Anthropic's prospectus and reported a 2025 net loss of nearly $42 billion on roughly $4.6 billion of revenue.23 The Telegraph said that figure would make Anthropic the most loss-making company ever to attempt a listing. One year of losses is larger than the $41.3 billion SpaceX had lost in total when it went public in June.8

The $2 trillion target is already being questioned. Reuters, citing four sources, reported that investors who attended Wednesday's meeting talked about a valuation closer to $1.5 trillion after looking at the latest numbers. My view is that the headline loss tells you less about this IPO than the reports suggest. The real tension is between Anthropic's growth and the very large spending commitments it has signed up for.

The $42 billion loss is mostly an accounting charge

The coverage broadly agrees that most of the $42 billion is not money spent running the business. Roughly $34 billion of it is a non-cash charge. It reflects the rising estimated value of earlier financing instruments that could convert into shares as Anthropic's private valuation climbed.36 Excluding those remeasurements, the 2025 operating loss was about $8.06 billion, up from $2.98 billion a year earlier.27

The operating figure is the one that tracks how the business actually performed. Total 2025 operating expenses were $12.65 billion. Computing and infrastructure accounted for $7.33 billion of that, or about 58%.7 Revenue rose from $386 million in 2024 to $4.59 billion, an increase of about 1,088%.7 Anthropic ended 2025 with $20.28 billion in cash, cash equivalents and short-term investments.6

Outlets presented the loss very differently. The Telegraph led with the record-loss angle and included critics' warnings about existential risk.8 Other analyses focused on separating the paper charge from real cash burn.310 Both approaches are defensible. Still, readers who saw only the $42 billion figure got a bleaker picture than the underlying business supports. An $8 billion operating loss on $4.6 billion of revenue is serious, but it is a different kind of problem from a $42 billion one.

2026 numbers changed the picture

The prospectus figures cover a company that looks quite different now. Quarterly revenue went from about $4.7 billion in the first quarter of 2026 to roughly $11.6 billion in the second and $16.8 billion in the third.5 Second-quarter revenue alone was more than double Anthropic's total revenue for 2025.6

The company prefers to report an annualized run rate. That measure stood at about $9 billion at the end of 2025, passed $47 billion by May 2026, and reached $65 billion by the end of July.6 The Financial Times reported that investors expect $100 billion to $120 billion by year-end.6

Profitability is where a careful reader should slow down. According to The Wall Street Journal, Anthropic's first adjusted operating profit came in the second quarter, at $559 million, and that figure excludes stock-based pay.9 The Telegraph noted that the company's claim of profitability in the first half of 2026 leaves out costs such as employee share compensation, and that including them would push it back into the red.8 The FT reported gross margins above 80%. That number is measured before revenue is shared with distribution partners.4 The company's rivalry with OpenAI also needs context. Anthropic's second-quarter revenue exceeded OpenAI's $6.7 billion, but Anthropic counts cloud-partner sales in full. That makes the two figures hard to compare directly.9

Some coverage also points to slowing growth. A 46% quarter-on-quarter gain is very fast for almost any company, but it is a smaller jump than the more-than-doubling in the quarter before.13 For a company asking to be valued on its growth rate, that change could matter in pricing talks. The shift in investor discussion toward $1.5 trillion fits that reading.

The $518 billion compute bill

The biggest long-term risk is Anthropic's spending commitments. The prospectus disclosed $518 billion in future cloud, computing and infrastructure obligations.7 Coverage disagrees on the timeframe. Some reports describe it as spending over the next decade.13 At least one crypto-news outlet says it will be spent within a single year, which is more alarming.19 The ten-year reading seems more plausible, and most outlets describe the figure simply as future obligations. Either way, the commitment is more than 100 times Anthropic's 2025 revenue.9

The FT reported a compute return of about 1.70 in recent results, meaning $1.70 of revenue for each dollar spent on compute. In 2025, the company earned only $0.63 per dollar of compute.13 That improvement is probably the strongest argument for the bull case. Chief executive Dario Amodei and finance chief Krishna Rao reportedly told investors that current margins could change as spending on compute and biomedical research ramps up. The FT also noted that rising interest rates could slow some infrastructure plans.13

There is also customer concentration risk. Nearly a quarter of 2025 revenue came from just two clients.1 Each accounted for about 12%.7

How the valuation got here

Anthropic's private valuation has risen extremely quickly. It raised $3.5 billion at $61.5 billion in March 2025 and $13 billion at $183 billion that September. It then raised $30 billion at $380 billion in February 2026.14 The Series H in May raised $65 billion at a $965 billion post-money valuation. It was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital, and included $15 billion of previously committed hyperscaler money.12 Amazon has invested $13 billion and can add up to $20 billion more if milestones are met.16 Alphabet agreed in April to invest up to $40 billion, with $10 billion committed immediately at a $350 billion valuation.17

Secondary markets have priced Anthropic higher than its last round. Trades between existing shareholders implied around $1.2 trillion by July.12 Perpetual futures on Hyperliquid reached an implied value of about $2.36 trillion in September.18 Those markets are thin and speculative, but they help explain why bankers aimed for $2 trillion. Reuters reported that the target relies partly on Anthropic's internal forecast of $190 billion to $200 billion in revenue by 2028.16 At $2 trillion, the multiple on the July run rate would be about 31 times. Against forecast 2028 revenue it would be closer to 10 times.12

Reported details of the deal itself vary. Reuters said the raise could reach $100 billion, and that Nvidia was discussing a cornerstone order of up to $10 billion.16 Euronews said the offering would raise more than $60 billion and named JPMorgan as a lead bank alongside Goldman Sachs and Morgan Stanley.18 The exact size will remain unclear until a public prospectus is filed.

What it means for AI funding

This IPO will be watched across private AI investing, because it is a direct test of whether private-market valuations hold up in public markets. A $2 trillion debut would beat the roughly $1.8 trillion at which SpaceX priced its listing in June. It would also be about double Anthropic's May valuation.11 OpenAI's last private round valued it at $852 billion. It filed confidentially a week after Anthropic, and talk around its own listing is in the range of $1 trillion.12

If Anthropic prices well, other AI labs will have a public benchmark, and venture investors will have a clearer path to selling stakes. If it prices closer to $1.5 trillion, that is still about 55% above the Series H. Early backers would still make large gains. But it would show that public investors are more cautious about adjusted profits and very large compute commitments than private investors have been.

The company also sends an unusual mixed message. Its prospectus warns that its own technology could pose existential risks to humanity, while it asks investors to fund faster development.1 Investors may not weigh that warning heavily. They will weigh the prospectus's risk factors and governance terms, and the company's founder-controlled structure gives public shareholders limited voting power.7

Anthropic is not a company in financial trouble. Most of the $42 billion loss is an accounting charge, and revenue is growing fast. The real question for investors is whether that growth can keep up with more than half a trillion dollars in compute obligations. The answer will determine whether the IPO prices near $2 trillion or settles closer to $1.5 trillion.
